You must dig deeper into US history. Citizenship was revoked or frozen en masse at certain period for different races. Actually the “free” USA only happened after world war 2 and it was probably because the US was becoming the super power.
This current administration wants to end interventionism which means the old US (100% white/all Protestant) might be coming back. If you are not in that category you must start planning accordingly.
Yes the Germans are really strict with their nationality. One thing I cannot fathom is how the Germans kept honouring the citizenship given to SS collaborators from other countries after the war.
In Holland we've had some war criminals (Dutch collaborators) that leisurely lived out their lives in Germany because they received citizenship through SS membership as thanks for their war crimes. And Germany doesn't extradite its own citizens. Also they stalled local prosecution until the people in question were too old and frail to stand trial.
I really don't understand how the western world let them get away with doing that. Every SS-derived citizenship should have been instantly revoked in 1945, all wartime laws retracted and citizens with wartime crimes extradited.

It was also revoked for American women who married foreign citizens until the early 20th century - in fact, an awful lot of my parents' friends for some reason still assume that I lost mine and automatically became a German citizen when I married my husband.
Ha. Getting German citizenship has become easier, but it's still far from automatic, and at least the way things have been the past 100 years or so, I (native-born to native-born US citizens in the US, white) would have to jump through a lot of hoops to get rid of my US citizenship.
